OTR used to have something called a session id (IIRC), which was
essentially a long version of an SAS. I think they removed it around the
same time they started using the Socialist Millionaire Protocol to do
shared secret auth, for usability reasons.

Nowadays, OTR clients just use a simple fingerprint comparison as the
"barebones" type of authentication.
